Chances for Pitt and Bentley University

Hi,

I attend an IB STEM school.

I take all IB courses, with two business specific classes. I want to major in Business.

I have a 3.7 on a 4.0 scale.

I got a 30 on my ACT (first try, am going to retake and actually study), and got a 1260 on my SAT.

So far, my dream school is Pitt Business School, with Bentley as number 2. What are my chances for both of them?

I am involved in multiple clubs like robotics, various sports, and class office. I have owned by own business for the past few years, which I am talking about in my short answer questions.

If I retake my ACT and get another point or two, can that make up for my GPA?
